Abstract. Tidal activity in the Mesospheric Lower Thermosphere (MLT) region over Trivandrum (8.5 N, 77 E) is investigated using the observations from newly installed SKiYMET Meteor Radar. The seasonal variability and vertical propagation characteristics of atmospheric tides in the MLT region are addressed in the present communication. The observations revealed that the diurnal tide is more prom...

STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...

[1] We examine tidal modulation and back-propagating fronts in simulated slow slip events using a rate and state friction law that is steady state velocity weakening at low slip rates and velocity strengthening at high slip rates. Tidal forcing causes a quasi-sinusoidal modulation of the slip rate during the events, with the maximum moment rate occurring close to or slightly after the maximum a...

Ariake Sound, in Kyushu Island of western part of Japan and connecting the small bay, Isahaya Bay, in the northwestern (Fig. 1) is strongly affected by large semidiurnal tide of which amplitude ranges from 3 to 5 m [3]. While Ariake Sound exhibits highly productive, red tides have occurred more frequently around the northern area of Isahaya Bay Mouth, causing damage to the sheries, recently [1]...

Single fibre and "integrated" phrenic nerve activity was recorded in anaesthetized spontaneously breathing rabbits, during experimentally induced lung oedema. Tidal volume, blood pressure, end-tidal CO2, were monitored. In oedema the number of impulses in each volley slightly decreased while the discharge frequency was increased relatively to control values. The latter effect was due to the inc...

Intertidal organisms may employ circatidal rhythms to track the tidal cycle, but tidal patterns may vary within a species range and necessitate adaptation to the local tides. Circatidal rhythms were examined in populations of the eastern Pacific fiddler crab Uca princeps (Smith) from four sites with differing tidal characteristics, La Paz (24 10¢N; 110 21¢W), San Blas (21 33¢N; 105 18¢W) and Ma...

Tide-induced hydraulic head fluctuation results in significant airflow above the water table if the aquifer is air-confined, for example, if the aquifer is capped by low permeability materials. Hypothetical studies on the interaction between tidal fluctuation and airflow in coastal aquifers are carried out using an air–water two-phase numerical model. The results show that both the amplitude of...

Zonal mean daytime temperatures from the Wind Imaging Interferometer (WINDII) on the Upper Atmosphere Research Satellite (UARS) and nightly temperatures from a potassium (K) lidar are employed in the study of the tidal variations in mesospheric temperature at low and mid latitudes in the Northern Hemisphere. The analysis is applied to observations at 89 km height for winter solstice, December t...

Spatial resource gradients have been observed at a number of proposed tidal energy sites. However, these gradients are typically quantified using the first or second moments (i.e., mean or standard deviation) of time series which obscures information about the co‐temporal amplitude and phase variation. These co‐temporal variations have a number of interesting implications for power production f...
